An AI agent modifies a Kubernetes manifest and silently drops an anchor reference. A GitHub Actions workflow gains an extra indent. A Docker Compose volume mapping loses its colon. YAML is the most dangerous config format for AI — whitespace-sensitive, deeply nested, and full of edge cases that break silently.

This MCP uses the yaml package (30M+ downloads) — the only JavaScript YAML library that passes the complete official YAML test suite — to parse and serialize with zero data loss.

parse_yaml

Pass the content and direction ("yaml-to-json" or "json-to-yaml"). This engine uses the yaml package (30M+ weekly downloads) which is more robust than js-yaml and passes the official YAML test suite. Converts YAML to JSON and vice versa. Supports YAML 1.1/1.2 with comment preservation. Essential for Kubernetes, GitHub Actions, Docker Compose, and Ansible configs

Convert this Kubernetes deployment manifest to JSON so I can programmatically modify the replica count.

JSON output with spec.replicas, containers, volumes — all fields preserved with correct types.

Our CI team needs the GitHub Actions workflow as JSON to validate it programmatically before merge.

Workflow parsed: jobs, steps, environment variables, and conditional expressions all converted to typed JSON.

Take this Docker Compose JSON config and generate valid YAML for the docker-compose.yml file.

Valid docker-compose.yml generated with correct indentation, service definitions, and volume mappings.

YAML is whitespace-sensitive. A single misplaced indent changes the entire structure silently — no error, just wrong behavior. AI models frequently hallucinate incorrect indentation, lose anchor references, and add trailing spaces. This engine validates against the real spec.
